The month of June holds a unique distinction in the world of gemstones, offering a trio of official birthstones that provide an unparalleled diversity of color, origin, and symbolism. Unlike months confined to a single gem, June celebrates the classic elegance of pearl, the ethereal glow of moonstone, and the transformative magic of alexandrite. Each stone tells a distinct story, representing purity, intuition, and change. This rich selection allows individuals born in June, or those who appreciate fine jewelry, to choose a gem that perfectly aligns with their personal style and spiritual intentions.
The existence of three official birthstones for June stems from a long history of gem appreciation. The pearl, the oldest of the trio, has been revered for centuries for its natural luster and organic origin. Moonstone, with its captivating adularescence, emerged later as a cherished gem of the Art Nouveau period. Alexandrite is a relatively modern addition, discovered in the 19th century and celebrated for its remarkable color-changing ability. Together, they form one of the most enchanting and versatile collections in the birthstone calendar.
The History and Lore of June's Gems
The historical journey of June's birthstones is as varied as the gems themselves. Each stone carries a legacy woven from ancient beliefs, cultural significance, and evolving traditions.
The Timeless Legacy of Pearl
The pearl stands as the most ancient of the June birthstones. As an organic gem created by living mollusks, its history is deeply intertwined with human civilization. Ancient cultures across the globe revered pearls as symbols of purity, wisdom, and serenity. Their natural elegance and rarity made them prized possessions of royalty and nobility for centuries. The pearl's symbolism extends beyond material wealth; it is often associated with emotional healing and the calming of the mind, offering inner peace and clarity to the wearer. This deep-rooted history solidifies the pearl's position as the classic, traditional choice for June.
The Mystical Allure of Moonstone
Moonstone's history is steeped in mysticism and connection to the celestial. For centuries, this gem has been admired for its unique visual effect, known as adularescence, which gives it a shimmering, otherworldly glow reminiscent of the moon. It has been deeply tied to the divine feminine, nurturing emotional balance and enhancing intuition. In various traditions, moonstone is believed to connect the wearer with lunar energy, promoting serenity and creativity. As a birthstone for the sign of Gemini, it is said to represent emotional duality and spiritual alignment, making it a powerful talisman for those seeking harmony.
The Modern Marvel of Alexandrite
Alexandrite is the youngest of the trio, with its history beginning in the early 19th century. Its discovery in Russia's Ural Mountains quickly made it a national treasure, prized for its extraordinary ability to change color from green in daylight to red in incandescent light. This color-changing property was seen as a symbol of the old Russian Imperial colors—red and green—and imbued the stone with an air of magic and good fortune. As a modern birthstone, alexandrite represents change, creativity, and awakening. Its rarity and captivating transformation have captured the hearts of gem enthusiasts, making it a symbol of duality and personal growth.
Geological Formation and Global Sources
The origins of these three gems could not be more different, spanning the biological, the geological, and the rare conditions that create color change.
Organic Origins of the Pearl
Unlike all other gemstones, pearls are not formed within the earth's crust but are created by living organisms. They are the product of a defense mechanism within mollusks, such as oysters and mussels. When an irritant, like a grain of sand, enters the mollusk's shell, it secretes layers of nacre—a composite of aragonite and conchoidal calcite—around the foreign body to protect its soft tissues. Over several years, these layers build up to form a lustrous pearl. Natural pearls are exceptionally rare; most pearls on the market today are cultured, where a human intentionally introduces an irritant to stimulate nacre production. Historically, the finest natural pearls were found in the Persian Gulf, the Red Sea, and the waters off India and Sri Lanka. Today, major sources of cultured pearls include Japan, China, Australia, and French Polynesia.
The Formation of Moonstone
Moonstone is a variety of the mineral feldspar, specifically orthoclase or albite. Its formation occurs within igneous and metamorphic rocks. The captivating adularescence is the result of an intergrowth of two different feldspar minerals—orthoclase and albite. As the stone forms, these layers are arranged in such a way that light entering the stone is scattered and diffracted, creating the signature sheen that seems to move across the surface. The finest moonstones are sourced from Sri Lanka, though significant deposits are also found in India, Myanmar, and Madagascar.
The Discovery and Rarity of Alexandrite
Alexandrite is a variety of the mineral chrysoberyl. Its formation requires a unique geological environment. The presence of chromium, which imparts the gem's green color, is typically incompatible with the growth of large chrysoberyl crystals. The original alexandrite was discovered in the Ural Mountains of Russia, where the combination of chromium and the right mineralizing agents allowed for the formation of these rare crystals. The color-changing phenomenon is due to the specific way the stone absorbs light; it is colored by the red wavelengths of incandescent light and the green wavelengths of daylight. While the Russian deposits are now largely depleted, other sources of alexandrite have been found in Brazil, Sri Lanka, and East Africa, though stones with the dramatic color shift of the original Russian material remain exceptionally rare.
Gemological Properties: A Scientific Profile
Understanding the physical and chemical properties of these gems is essential for both gemologists and jewelry buyers. These characteristics determine not only the stone's beauty but also its durability and care requirements.
Pearl
Pearls are unique in their composition. They are primarily made of calcium carbonate in the form of aragonite or calcite, arranged in a crystalline structure. Their hardness on the Mohs scale is relatively low, ranging from 2.5 to 4.5, and they possess no cleavage. This makes them susceptible to scratches and damage from acids, cosmetics, and even perspiration. Their luster, or the intensity and quality of light reflected from their surface, is a key indicator of quality.
Moonstone
As a member of the feldspar group, moonstone has a hardness of 6 to 6.5 on the Mohs scale. Its chemical formula is a complex mix of aluminum silicate with potassium or sodium. While reasonably durable, it has perfect cleavage in two directions, meaning it can be easily fractured if struck with force. This property makes it crucial to protect moonstone jewelry from sharp impacts. Its most valued characteristic is the quality of its adularescence, with the best stones displaying a vivid, blue sheen moving across a clean, colorless body.
Alexandrite
Alexandrite is a very durable gemstone, making it an excellent choice for all types of jewelry. It registers an 8.5 on the Mohs scale, second only to diamond, corundum (ruby and sapphire), and chrysoberyl (including alexandrite itself). Its chemical composition is beryllium aluminum oxide (BeAl₂O₄) with chromium as the color-causing impurity. It has no cleavage, giving it good toughness. The most prized alexandrite exhibits a strong color change from a vivid green or bluish-green in daylight to a rich raspberry red or purplish-red in incandescent light.
| Gemstone | Mineral Family | Chemical Composition | Mohs Hardness | Key Characteristic |
|---|---|---|---|---|
| Pearl | Organic (Aragonite/Calcite) | CaCO₃ | 2.5 - 4.5 | Luster, Organic Origin |
| Moonstone | Feldspar (Orthoclase/Albite) | KAlSi₃O₈ - NaAlSi₃O₈ | 6.0 - 6.5 | Adularescence |
| Alexandrite | Chrysoberyl | BeAl₂O₄ | 8.5 | Strong Color Change |

Choosing a June Birthstone by Date
An interesting tradition aligns specific dates within June with particular gemstones, offering a more personalized choice for those born in the month.
- June 1–15: Individuals with early June birthdays, such as those born on June 6, 11, 12, or 15, are traditionally aligned with the Pearl. This gem is said to bestow its calming and balancing effects, making it ideal for those who value inner peace and timeless beauty.
- June 16–30: Those born in the latter half of the month, including birthdays on June 16, 21, 22, 23, 24, 25, 26, 27, 28, 29, and 30, tend to be drawn to the transformative energy of Alexandrite or the intuitive glow of Moonstone. These stones are believed to enhance creativity and spiritual alignment during the peak of summer.
Care and Cleaning
Proper care is essential to maintain the beauty of these gems, with requirements varying based on their unique properties.
Pearl: Due to their softness and organic nature, pearls require gentle handling. They should be the last thing you put on and the first thing you take off. Clean them with a soft, damp cloth after each wear. Avoid exposing pearls to chemicals, including perfume, hairspray, and cosmetics, as these can erode their luster. Store them separately to prevent scratching.
Moonstone: With a moderate hardness of 6-6.5, moonstone can be cleaned with warm, soapy water and a soft brush. However, its perfect cleavage means it should be protected from hard knocks and extreme temperature changes. It is best stored in a soft pouch away from other jewelry.
Alexandrite: As a very durable gem with an 8.5 hardness, alexandrite is easy to care for. It can be safely cleaned using warm, soapy water and a soft brush, an ultrasonic cleaner, or a steam cleaner. Its toughness makes it an excellent choice for rings and other jewelry worn daily.
